Abstract
An expansion turbine with a radial turbine wheel has a main path that gradually increases in height and axially discharges fluid while swirling from a main inlet located at the outer circumferential side into the main path, with a radial flow as a main component, the radial turbine wheel has a sub-path branching off from the side of a hub of the main path at a position radially inward of the main inlet and extending rearward from the main path, the sub-path has, at an outer circumferential end, a sub-inlet located at a position in the radial direction different from the main inlet and supplied with a fluid having a pressure different from the pressure of the fluid supplied through the main inlet, the main inlet and the sub-inlet are partitioned by a back plate portion, in which the gap between it and the main path or the sub-path is adjusted.
